The ATLAS detector at the Large Hadron Collider is used to search for high-mass resonances decaying dielectron or dimuon final states. Results are presented from an analysis of proton-proton (pp) collisions a center-of-mass energy 8 TeV corresponding integrated luminosity 20.3 fb-1 in channel and 20.5 channel. A narrow resonance with Standard Model Z couplings fermions excluded 95% confidence level masses less than 2.79 channel, 2.53 2.90 two channels combined. Limits on other model...
This document is the final report of ATLAS-CMS Dark Matter Forum, a forum organized by ATLAS and CMS collaborations with participation experts on theories Matter, to select minimal basis set dark matter simplified models that should support design early LHC Run-2 searches. A prioritized, compact benchmark proposed, accompanied studies parameter space these repository generator implementations. also addresses how apply Effective Field Theory formalism for collider searches present results...
This document a outlines set of simplified models for dark matter and its interactions with Standard Model particles. It is intended to summarize the main characteristics that these have when applied searches at LHC, provide number useful expressions reference. The list includes both s-channel t-channel scenarios. For s-channel, spin-0 spin-1 mediations are discussed, also realizations where Higgs particle provides portal between visible sectors. guiding principles underpinning proposed...
This report of the BOOST2012 workshop presents results four working groups that studied key aspects jet substructure. We discuss potential first-principle QCD calculations to yield a precise description substructure jets and study accuracy state-of-the-art Monte Carlo tools. Limitations experiments' ability resolve are evaluated, with focus on impact additional (pile-up) proton collisions performance in future LHC operating scenarios. A final section summarizes lessons learnt from analyses...

This report summarises the physics opportunities in search and study of beyond Standard Model at a 100 TeV pp collider.
Particle physics has an ambitious and broad experimental programme for the coming decades. This requires large investments in detector hardware, either to build new facilities experiments, or upgrade existing ones. Similarly, it commensurate investment R&D of software acquire, manage, process, analyse shear amounts data be recorded. In planning HL-LHC particular, is critical that all collaborating stakeholders agree on goals priorities, efforts complement each other. this spirit, white paper...

Colliders, among the most successful tools of particle physics, have revealed much about matter. This review describes how colliders contribute to search for dark matter, focusing on highest-energy collider currently in operation, Large Hadron Collider (LHC) at CERN.

Finally, it...
Weakly-coupled TeV-scale particles may mediate the interactions between normal matter and dark matter. If so, LHC would produce through these mediators, leading to familiar "mono-X" search signatures, but mediators also signals without missing momentum via same vertices involved in their production.

In this work, we consider the case of a strongly coupled dark/hidden sector, which extends Standard Model (SM) by adding an additional non-Abelian gauge group. These extensions generally contain matter fields, much like SM quarks, and fields similar to gluons. We focus on exploration such sectors where dark particles are produced at LHC through portal undergo rapid hadronization within sector before decaying back, least in part potentially with sizeable lifetimes, particles, giving range...

Abstract In modern High Energy Physics (HEP) experiments, triggers perform the important task of selecting, in real time, data to be recorded and saved for physics analyses. As a result, trigger strategies play key role extracting relevant information from vast streams produced at facilities like Large Hadron Collider (LHC). energy luminosity collisions increase, these must upgraded maintained suit experimental needs.
